This is fine to me. Actually I didn't know there was the possibility of an
function object. Because there was this web/knot/bunch/heap of connect
declarations, which I never scanned if not _forced_ to.

I prefer connect_to_functionobject, since connect a signal to a signal ... are
these really the same species? This would confuse people a lot if there is only
the slightest difference.

The old code was ambiguous and difficult to read. Kill it!

Perhaps provide a have_to_explicitely_state_so define (-DOLD_CONNECT) which
provides the old syntax for the poor end-user trying to compile old stuff. You
can warn like hell, but there might be old stuff around for a while.
